I don't have decklink hardware but I assume it never outputs actual transparency. Or does it?
From what I understand about SDI, it is possible to send alpha information over an SDI link in certain configuration (RGBA) -- from what I read on Wikipedia ( https://en.wikipedia.org/wiki/Serial_digital_interface#Link_numbering ) on SDI. I will assume that it might be possible to access that information from such a decklink card (I don't have and SDI hardware as of yet, but might end up getting one)
